vSIGrNMENTS, TO THE HUGHES RATION OF OHIO.

Applicata HOLLNAGEL,

OF MILWAUKEE, WISCONSIN, ASSIGNOR, BY INIESNE .AS- -KEENAN COMPANY, OF MANSFIELD, OHIO, A. CORPO- TRUCK.

This invention relates to certain new and useful improvements 1n trucks and refers more particularly a load from the body to means for discharging thereof.

The present manner of constructing trucks equipped with charging of the mounting the means for facilitating disload therefrom is by tiltably body and raising its inner end either by hoist cables or hydraulic means. This manner of discharging the contents of the truck body is objectionable in that veX- cessive power is required and furthermore that its operation is not as smooth or efficient as is desired.

Therefore, having the above in mind, it is one of the objects of this invention to provide an improved type of means for discharging material from a truck body in which the body is fixed and discharged by being bodily shifted toward the discharge end.

It is another object of this invention to rovide a load receiving body having a movable bottom and means for moving the bottom to and from the body discharge end,

whereby materi from the body.

Another object al may be readily discharged of this invention resides in the provision of a device of the character described having a movable bottom or oor for the load receiving equi ped with means liody is bodily shifted toward the disthe body thereof whereby a load within for adjusting the This invention has for a capacity thereof.

further object to provide a device of the character described having means for scraping the sides of the load receiving body to prevent adhering of material to the walls thereof after the load has been discharged therefrom.

A still further object of this invention resides in the provision of a device o f the character described which may be applied to trucks now in use or to trucks at the time of their manufacture..

With the above and which will appear as ceeds, my invention resides in the novel con-v struction, lcomb other objects in View the description proination and arrangements of ion led J'une 19, 1922, Serial No. 569,516. Renewed March 17, 1928.

tparts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

.Figure 1 is a side view of the rear portion of a truck equipped with my invention, parts thereof being broken away and in section;

Figure 2 is a sectional view taken transversely through Figure 1 on the plane of line 2-2;

Figure 3 is a fragmentary detail view illustrating the construction of the movable load receiving body floor;

Figure 4 is a detail view illustrating the manner of connecting the movable 'loor with a pipwer takeoff` shaft of the truck power uni Figure 5 is a side fragmentary view of the rear portion of a truck equipped with a slightly modified form of movable load receiving body bottom, and .i

Figure 6 is a fragmentar detail=view illustrating the means carrie by the movable load receiving body floor inner end for: removing material from the body side walls.

Referring now more particularly "to the accompanying drawings, in which like :numerals designate like parts throughout the several views, the numeral 10 designates the chassis frame of an automotive truck which is supported at its rear by drive wheels 11 and at its forward end by steering wheels, not shown. Mounted on the chassis frame, rearwardly of the power unit, not shown, is a load receiving body supporting frame coinprising longitudinal side channel beams or sills 12 that arespaced from the chassis frame by transverse beams or bars 132, and carry, at spaced intervals, `transverse bars or channel beams 14 upon which vis mounted a load receiving body 15 having side wallsl locked in closed position by a locking rod 18 controlled by an actuating lever 20. ,The bottom of the body is formed by a lurality of transverse plates 21, the interme late portions of which are offset, as at 22, to dispose their ends on different planes whereby the ends of adjacent plates overlap and form a substantial y leve floor.

Each plate' 21 has one or more links 23 secured thereto, and adjacent longitudinally aligned links are iivotallyconnected, as at 24, to form s roc ret chalns for` connecting the plates. T ere are a suliicient number of plates 21 so that, with the parts in their position illustrated in Fi re 1, the bottomwill extend throughout t e entire length of the body. The opposite ends of the sprocket chains formed by links 23 suitable cable or sprocket chain means 25 which train about sprocket wheels 26 and 27 mounted on shafts 28 and 29 journaled in bearings disposed adjacent the forward and rear ends of the truck body, respectively. The shafts 28 and 29 and sprocket wheels 26 and 27 are so positioned that lates 21 are on the proper plane to form t e floor of the bod Disposed along the lower longitudinal edge of each side 16 is a strip 30 on which the adjacent ends of plates 21 ride and the intermediate portions of said lates are braced by lon itudinallygexten lng strips thc bottom of the body,

4 discharge o 31 connectingt e brace beams 14. The material within the truck body is preventedfrom working over the edges of the plates by guards 32 carried by sides 16 and inclined inwardly therefrom to overlie the ends of the movable Hoor, see Figures 1 and 2.

As before described, the rear discharge end ofthe truck ing gate which may opened to permit discharge of' materials therefrom. The discharging of material from the truck body is accomphshed by moving the plates, forming. toward the discharge end and to insure the positive expelling of al1 material, an end plate member or partition 33 is carried by the inner end of the movable floor and insures the bodily shifting of the material with the movable floor.

Member 33 has its inner cured to one of the innermost plates 21, .as at 34, and is braced by a plate 35, the upper longitudinal edge of which is pivotally secured to plate member 33 at an lntermediate point, as at 36, and the lower longitudinal edge of which is detachably secured, as at 37, to one of the plates 21 spaced inwardly from the plate carr ing said end member. ln this manner, mem r 33 is not only braced but rovided ,whereby the ositive all material is assured w en the ttom is moved to position member 33 at its extreme outermost position, as best illustrated by the dotted lines in Figure 1.

end rigidly Se- Member 3 3 not only shiftingof the load with the movable Hoor, but permits the ready ad'ustment of the dy to measure any part o a load. As for instance, if it is desired to measure a half of a load, memberb33i is shifted to a position The movable floor- ?7 is actuated by rotating shaft 29 in either direction, according to whether it is desired to return the floor to normal position or to discharge the contents of the truck body, and this is accomplished by connectin said shaft with a drive shaft 38 bi sproc et wheels. 39 and `40, and a sproc et chain 41. The shaft 38 is journaled in bearings carried by beams 12 and is connected, b gearing 42, with a drive shaft 43 journale in bearmgs carried by beams 12.

.Journaled in certain of the transverse beams 13, 'adjacent shaft 43, is a shaft 44,

which is drlvingly connected with the shaft, 43, by gearing 45, and has fixed thereon a- `whereby sprocket wheel 48 maybe made fast to the counter shaft. The counter shaft 49 a sprocket chain 53, with a sprocket wheel 54 freely rotatably mounted on a shaft 55 which derives its power from the power unit of the truck, not shown. As best illustrated in Figure 4, sprocket wheel 54 is drivinvly connected and disconnected with shaft 55Il1y insres the bodily has a drive sprocket 52 mounted thereon which is connected, by

a clutch member 56 which is capable of actu-v l positioned adjacent the drivers seat. Gear 50 may be meshed with gear 46 or actuated to make sprocket 48 fast with the counter shaft by manipulation of a pedal 58 positioned adjacent the drivers seat.

When it is desired to discharge a load within the truck body, pedal 58 is actuated to meshy ears 50 and 46 and lever 57 is moved to male sprocket wheel 54 fast to shaft 55, as a result of which the movable-floor is then actuated to advance member 33 toward the discharge end of the truck as will be readily obvious: After the load has been discharged and it is desired to place the truck bod in condition to receive another load, the dil-ive is reversed by disconnecting gears 50 and 46 and shift'ng gear 50 to make sprocket wheel 48 fast to the counter shaft.

Any material tending to adhere to the sides 16 of the truck body is removed by ation by a lever 57 means of Scrapers 59 carried bymember 33 and yieldably urged to engagement with the side walls by a spring 60', see Figure 6.

In Figure 5 I have illustrated a slightly modified form of my invention in which the outer end of the movable floor winds upon a drum 60 when the truck load is being discharged, drum 60 being driven with shaft 29 bya sprocket and chain connection 61, but at a slower speed to compensate for its increase in diameter as the floor is wound therearound.

In this form of my invention the drive is illustrated as b means of a hand crank 62 carried by a slaft 63 which is in geared connection with shaft 29, shaft 29 and shaft 64 of drum 60 being carried by combined braces and shields 65. Guards 66 are employed to prevent 'slipping of links 23 of the sprocket wheels 27.

Tofinsure the easy control of the movable floor, a roller 67 is freely rotatably mounted on each pivot 24. The rollers 67 project below the links 23 and track on a floor or other support 68 to relieve the load from being directly carried by the chains formed by links 23.

What I claim as my invention is:

l. A device of the character described, comprising a load receiving body having a discharge end, an end member normally positioned adjacent the end of the body remote from the discharge end,'means operable to move said member toward the discharge end of the body to expel material within the body therefrom through the discharge end, Scrapers secured along the sides of said member, and spring means yieldably urging said Scrapers to engagement with the walls of the load receiving body to remove material adhering thereto as said member is moved.

2. A device-of the character described, comprising a load receiving body having a stationary floor, a movable floor for the body, longitudinal supporting strips mounted on the stationary ioor in parallel, spaced relation and supporting and spacing the movable fioor from the stationary Hoor and providing longitudinal braces for the movable floor, a plurality of sprocketchains longitudinally secured to the movable Hoor in spaced relation medially of said supporting strips, and roller members carried by the sprocket chains and projecting therebeneath to track on said stationary floor whereby the movable floor1 is supported and braced by said supporting strips and the sprocket chains.
